What are the methods for preventing prostate cancer? What should men do to prevent prostate cancer? Prostate cancer, a disease that surprises men, has brought many shadows to normal life. Prostate cancer is a type of prostate disease that is exclusive to men. This type of cancer often exhibits familial aggregation, and studies have shown that genetics is one of the causes of prostate cancer. In addition, some exogenous factors can also induce the emergence of prostate cancer. So, how can this disease be prevented?
One of the causes of prostate cancer is genetics
If an immediate relative (brother or father) has prostate cancer, their risk of developing prostate cancer doubles. The relative risk of prostate cancer among two or more immediate family members increases by 5-11 times. A subset of the population with prostate cancer (approximately 9%) is "truly hereditary prostate cancer," which refers to the presence of 3 or more relatives or at least 2 early onset (before the age of 55).
Epidemiological studies have found that patients with a positive family history of prostate cancer have a diagnosis age of approximately 6 to 7 years earlier than those without a family history, with no other differences. The probability of prostate cancer detected by needle biopsy is approximately similar in different regions of the world. This is in sharp contrast to the significant differences in the incidence of prostate cancer in different regions, with the highest rates in the United States and Northern Europe and the lowest in Southeast Asia. However, epidemiological studies have found that the incidence rate of Japanese immigrants to Hawaii has increased. If Japanese immigrants to California, the incidence rate has significantly increased and is close to the incidence rate of the United States.
The above research shows that exogenous factors can affect the progression from so-called latent prostate cancer to clinical prostate cancer. These factors, such as food intake, sexual behavior, alcohol consumption, ultraviolet radiation exposure, and occupational exposure, are still under discussion as possible etiological factors, but a high animal fat diet is an important risk factor. Tomatoes contain lycopene, a powerful antioxidant that is currently being extensively studied as a possible protective agent against prostate cancer progression.
A meta-analysis comprising 11 case control and 10 cohort studies was conducted to identify the association between tomato consumption and the risk of prostate cancer. The results showed that consuming large amounts of tomato reduced the relative risk of prostate cancer to 0.81 (CI 0.71-0.92). Other risk factors include low intake of vitamin E, selenium, lignans, and isoflavones.
